Up until now for I have been upgrading PS and LR as and when they were updated, as a matter of habit more than for new features. I cant say that I like the idea of CC, for more reasons than price, but that itself is another topic! I have no interest in the current PS CC tools like blur reduction and am happy with CS6. Lightroom 5 doesn't have anything immediately 'must have' but I would like to keep it up to date. I'm in a quandary as to whether I should pay for the perpetual licence or wait until a kick ass CS# is released and then grumble and go the CC route, where LR5 would be included.What are your thoughts on this?

I don't want to end up being Adobe's b!tch with CC ... I already have CS6 and it is more than adequate for my needs and I will buy LR5 tomorrow (just received an email that it will be released tomorrow) ... that's it for me.

I upgraded because its the main software that I use. In fact, it may be the reason I finally upgrade my desktop to 10.8! i'm still in 10.6.8... I;ve managed to doge other reasons to upgrade.... LR may make me do the jump.

As a pro landscaper I would like to keep LR up to date but don't see anything immediately 'must have' either. With LR now included in CC, the demand for the perpetual version will be lower. I therefore wouldn't be surprised if the full version (or maybe the upgrade version) of LR5 is available at an offer price sooner rather than later. This could be sold on Ebay etc if a kick ass CS# is released with LR5 included.

Yes I would like to upgrade from 4, I like being up to date regardless of how many new features are/aren't on it.

Now a question for you guys from me: If I do upgrade from my current LR4, does the entire program start fresh, losing all of my LR4 photos and presets/plugins. Also, when going the "upgrade" route rather than buying the entire program, do I get the same exact program but just cheaper because I'm upgrading?

The LR5 beta version, I am currently using, automatically detected all my LR4 presets & plugins ... so I see no reason it wouldn't on the upgrade version. If you have LR4 Catalogues it will also detect them and you will not lose any of your photos.

Thanks for the comments. Myself I am currently leaning towards waiting, though I am more interested in the new LR features than the PS CC ones and would like to eventually upgrade LR, if even only because of habit. I have a concern that the camera raw version in CS6, that I want to keep perpetual, wont be up to date with the new LR, based on what happened the last time. In the new Lightroom does anyone know whether when you 'edit in PS the image needs to be rendered by LR5 or can it be passed through as normal?Thanks

If you are choosing "upgrade", no, your LR 4 will not remain as a separate program. You get to keep your older LR4 & the newer LR5 as separate programs only if you buy the full version of the LR5 program.
